Okay, nostalgia time. When I read that Jane’s Addiction would be returning to Lollapalooza this year, I got a little verklempt. See, it got me thinking back to 1991, the year of the very first Lollapalooza festival, which everyone remembers as the one headlined by the festival’s creator Perry Farrell and his band Jane’s Addiction. But for me, 1991 was the year that alterna-rock/post-punk legends Siouxsie and the Banshees played the mega-fest, breaking into the U.S. mainstream on a bigger platform than ever before. I am among the hugest, most devoted Siouxsie fans on earth, so the Banshees’ participation in that tour was electrifying for me. Too bad I never got to witness their Lollapalooza magic. I did have tickets (of course I did! My sister and I slept outside overnight to get them!), but Sioux lost her voice and the band ended up canceling the two nights that my 16-year-old self would have been going apoplectic at Great Woods in Mansfield, Mass. I had seen the Banshees before Lollapalooza and went on to see them (and The Creatures and Siouxsie solo) many times after, but I never quite got over the heartbreak of missing this historic event. Interviewing Siouxsie with my sis in 1992 on ridiculously made-up credentials, then by myself as a legitimate journalist for a 2004 EW story helped ease the pain — a lot. And I can always console myself with the video below, in which the Banshees perform their 1988 ode to love, “The Last Beat of My Heart,” at the ’91 fest. (Note how the adoring crowd goes nuts at the 0:40 mark…right when Siouxsie takes the stage. Aw yeah. Also, love the gypsy head garb, Siouxsie.) Tell me, PopWatchers, what monumental (to you, anyway) pop culture events do you regret missing?
